The Lowdown
Righto, grab a coffee and settle in, ’cause I’ve been staring at the charts for Karramarro, and it’s a bit of a mixed bag. This is a classic point break setup, exposed to the NW, and it’s got some real potential, but it’s also a finicky spot that’s inconsistent. So, don’t go expecting a party wave every day.
The first real window of opportunity kicks off on Sunday the 6th of September. Sunday morning is the standout of the whole outlook. We’ve got a solid 5ft NW groundswell rolling in with a 12-second period, and the combined swell energy is chunky at 723. The wind is glassy from the S, which means it’ll be clean as a whistle. This is for advanced surfers only, though, 'cause that size is pushing the limits for anyone not comfortable in decent-sized waves. It’s the best on offer, no question.
Monday morning the 7th is still a good call. The swell drops to 3ft from the NW, but the period is a shorter 9 seconds. Still, with glassy conditions again, you’ll get some fun, clean waves. It’s a solid option for a morning session.
Now, take a look at Wednesday the 9th of September. The swell jumps up to 10ft from the NW, with a massive combined energy of 1163. That’s a lot of water moving. But the wind is howling at 15 mph from the NW, making it a cross-shore mess. The surf will be poor, and honestly, that much power with that wind is going to be a washing machine. For a point break, this setup often looks more interesting for kite surfers than paddle surfers. The same goes for the afternoon, with 7ft and still onshore winds.
We then hit a real dry spell. From Thursday the 10th right through to the middle of the month, the conditions are pretty ordinary. There are small waves, some glassy mornings, but the energy is weak (under 300), and the scores are low. It’s a stretch of about 5 to 6 days where you’re better off doing something else.
Things start to look a little more promising again on Tuesday the 16th of September. The morning session has a clean 3ft NW swell with a 13-second period and a light cross-offshore wind from the WNW. The combined energy is 349, and it’s described as "clean". It’s not a massive day, but it’s a good, surfable wave.
Then, on the 17th of September, Thursday morning, it’s similar. 4ft NW swell, 11-second period, combined energy of 334, and a clean cross-offshore breeze from the W. Again, a solid, user-friendly option.
Finally, circling back to the 19th of September, a Saturday morning picks up. 4ft NW swell, 10-second period, combined energy of 335, and it’s dead glassy with no wind. That’s a recipe for a great, clean morning session. Keep in mind, this is a long-range call, so it’s promising but not a guarantee.
So, for the best bet, get in the water on Sunday morning, the 6th of September. If you miss that, the mornings of the 16th, 17th, and 19th of September are your next best shots. Remember, this spot can be inconsistent, so when it’s on, you’ve got to go.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
